MdeModulePkg/DxeCorePerformanceLib: Fix incorrect size calculation

2025-03-26T01:59:01+00:00

The values of BootRecordDataPayloadSize and CommSize are incorrect. BootRecordDataPayloadSize should equal to SmmBootRecordDataSize - SmmBootRecordDataRetrieved CommSize should equal to OFFSET_OF (EFI_MM_COMMUNICATE_HEADER,Data) \ + (UINTN)MmCommBufferHeader->MessageLength SmmCommData->BootRecordSize should be set to BootRecordDataPayloadSize, instead of the total size of entire Smm boot record data.

MdeModulePkg: Add Standalone MM Core performance support

2025-03-21T15:23:11+00:00

Adds a new library instance to support MM core functionality for performance in Standalone MM. - Add StandaloneMmCorePerformanceLib instance - Move common MM logic to a new file `MmCorePerformanceLib.c` - Define interfaces with implementation specific to MM environment type in `SmmCorePerformanceLibInternal.h` and implement those functions in the Standalone MM and Traditional MM specific C files Note: StandaloneMmCorePerformanceLib supports both `MM_CORE_STANDALONE` and `MM_STANDALONE` as some Standalone MM environments have privilege separation and need to link this functionality in a ring 3 Standalone MM driver that is outside the ring 0 Standalone MM core driver.

MdeModulePkg/DxeCorePerformanceLib: Use EFI_MM_COMMUNICATE_HEADER

2025-03-21T15:23:11+00:00

Refactor the file to use the new type name EFI_MM_COMMUNICATE_HEADER. This is the same type but follows the new name and is more clear with upcoming Standalone MM support being added. Signed-off-by: Michael Kubacki

MdeModulePkg/DxeCorePerformanceLib: Install BPDT in config table

Install the performance table into the UEFI configuration table. This will allow the shell application to get this if the system is not using ACPI. Signed-off-by: Jeff Brasen Reviewed-by: Liming Gao

MdeModulePkg/DxeCorePerformanceLib:fix smm perf issue

2023-08-30T11:20:29+00:00

Fix smm perf issue in DxeCorePerformanceLib. In current code logic, total SMM perf record is copied multiple times to FPDT table if multiple ReadyToBoot events are signaled. This patch changes the function InternalGetSmmPerfData() to only get newly generated Smm perf data. Then previous generated Smm perf data won't be copied to FPDT again.

MdeModulePkg/FPDT: Lock boot performance table address variable at EndOfDxe

2021-11-12T07:36:23+00:00

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2957 1. Allocate performance data table at EndOfDxe and then lock the varible which store the table address at EndOfDxe. 2. Enlarge PCD gEfiMdeModulePkgTokenSpaceGuid.PcdExtFpdtBootRecordPadSize from 0x20000 to 0x30000 in order to hold the Delta performance data between EndOfDxe and ReadyToBoot. 3. SMM performance data is collected by DXE modules through SMM communication at ReadyToBoot before. Now to do SMM communication twice, one for allocating the performance size at EndOfDxe, another is at ReadyToBoot to get SMM performance data. 4. Make SmmCorePerformanceLib rather than FirmwarePerformanceSmm to communicate with DxeCorePerformanceLib for SMM performance data and size.

MdeModulePkg/DxeCorePerformanceLib: Switch to UnicodeStrnToAsciiStrS

2020-07-21T14:47:24+00:00

UnicodeStrToAsciiStrS requires that the source string is shorter than the destination buffer and will ASSERT if this is not true. Switch to UnicodeStrnToAsciiStrS as there are cases where the source string is longer than the buffer allocated for the device path. Signed-off-by: Jeff Brasen Reviewed-by: Dandan Bi
